Friedrichshafen FF.63

The Friedrichshafen FF.63 was a German prototype floatplane fighter produced by Friedrichshafen Aircraft Construction Company (Flugzeugbau Friedrichshafen) in the last year of the First World War. The aircraft was developed as a competitor to the Hansa-Brandenburg W.29 floatplane fighter already in service with the Imperial German Navy's (Kaiserliche Marine) Naval Air Service (Marine-Fliegerabteilung) and was heavily influenced by its design. The aircraft was still conducting flight testing when the war ended in November 1918 and the program was cancelled.
